Hi i ran a check on my databases via cpanel and i am getting quite a few of these in different tables.

for example:

xxxxxx_xxxxxx.ow_base_cron_job
warning  : 5 clients are using or haven't closed the table properly
status   : OK

The problem is there is noone online so im wondering if you all might do some checking on your own db and see if you have these warnings as well.  My thought here is that we should be closing the table properly regardless.  

some of the tables i recieved these on are notification_send_queu, ow_base_comment, base_comment_entity, base_user, base_user_online,mailbox_conversation, the majority of the mailbox and newsfeed tables, as well as others

i ran repair and it does seem to repair fine, i will watch to see if i get them again.
